IPC: F24H1/00
Filed: 1990-02-27
Abstract: PURPOSE:To close a backflow preventing chamber closing valve under a small water pressure by a construction wherein a waterpooling hopper opened for the air is provided under a backflow preventing chamber and the aforesaid valve is provided between the hopper and the backflow preventing chamber, while a hollow cavity is formed in the main body of the valve, at a position whereat a water flow is received. CONSTITUTION:When a drop closing valve 4 is opened from a state shown in the left halves of a first check valve 6 and a backflow preventing chamber closing valve 11 in the figure, water flows into a backflow preventing chamber 5 from an inlet 27. The water flow collides with the inside of a hollow cavity 40 and pushes the valve 11 downward by the kinetic energy thereof. On the occasion, the weight of hot water collected in the cavity 40 is also added and thus the flow surmounts the activating force of a spring sufficiently. When the valve 11 is pushed down, a rubber packing 42 of the valve 11 comes into pressure contact with a partition plate 21 and blocks up a drain hole 22. In this way, the water pressure received by the whole of the valve 11 and the valve 11 is left closed. At this time, accordingly, the hot water flowing into the chamber 5 fills up the chamber without leaking onto the water-pooling hopper 9 side, and moreover, it is supplied onto the second check valve accommodating chamber 24 side and further onto the circulation circuit side.

Title: Dioxolane derivative and manufacture
Inventor: FUIRIITSUPU NEIRU EDOWAAZU
IPC: C07D317/34
Filed: 1981-04-03
Abstract: The invention is concerned with novel dioxolane derivatives of the formula:   <IMAGE> I  in which Ra is hydrogen or (1-4C)alkyl and Rb is (1-4C)alkyl or phenyl optionally bearing a halogeno substituent; their production; and their use for the manufacture of certain known anti-arthritic acids of the formula:   <IMAGE> V  and, in particular, those acids in which Ra=Rb=methyl or Ra=ethyl and Rb=phenyl, by a novel reduction process. The preferred reduction procedures involve the use of an alkali metal borohydride or cyanoborohydride in the presence of a noble metal catalyst, or the use of an  alpha -branched alkyl or cycloalkyl Grignard agent. The use of the derivatives of formula I avoids the need for potentially toxic reagents and reactive intermediates in the previously known processes for the production of the acids of formula V.

Title: Triangle wave generator
Inventor: MICHIYAMA KATSUNORI
IPC: H03K4/06
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a triangle wave signal having a stable frequency by setting a charging circuit of a capacitor while a terminal voltage of the capacitor is lower than a reference voltage fed to a comparator circuit thereby setting a generated voltage from a reference voltage generating circuit to the 1st reference voltage switchingly. CONSTITUTION:When a terminal voltage VC of a capacitor CT reaches a voltage VH, an output of a comparator circuit 13 is inverted into a high level and switch elements S1, S2 are turned on. Thus, in this stage, a reference voltage Vref fed to the comparator circuit 13 is expressed as R1XI=VL, the capacitor CT is discharged via the switch element S1 and the 2nd constant current circuit 12 and the voltage VC is decreased in proportion to a time (t). When the terminal voltage VC of the capacitor CT reaches the reference voltage VL, the output of the comparator circuit 13 is inverted again into a low level and the capacitor CT is subject to charging control. Thus, a triangle wave is generated at the terminal of the capacitor CT succeedingly.
